Subject: Re: Can it be possible in j2ee architecture ?
Hi,
I'm sorry that my language was not enough straight
forward to put the question.
Anyway, u have understood the problem correctly:
I want to refresh the page asynchronously. So no
question of refreshing at n sec intervals. It should
be immidiately updated whenever the bean updates the
table.
applet ,as u told, may create problem. So any other
solution related to jsp or DHTML?
Thanks and Regards,
sudarson
